Lungendurchblutungsstörung

Lungendurchblutungsstörung, also known as pulmonary perfusion disorder, refers to a condition where the blood flow through the lungs is impaired. This can occur for various reasons, affecting the ability of the lungs to efficiently transfer oxygen into the bloodstream and remove carbon dioxide. A primary cause of lungendurchblutungsstörung is pulmonary embolism, a blockage in the pulmonary arteries usually caused by blood clots. Other conditions that can lead to reduced blood flow include pulmonary hypertension, where the pressure in the lung arteries is abnormally high, and chronic obstructive pulmonary disease (COPD), which can damage lung tissue and affect blood vessels. Congenital heart defects that involve abnormal blood flow between the heart and lungs can also result in perfusion issues. Symptoms can vary depending on the severity and underlying cause, but may include shortness of breath, chest pain, coughing, and a bluish discoloration of the skin (cyanosis). Diagnosis typically involves imaging tests such as chest X-rays, CT scans, and ventilation-perfusion scans, as well as pulmonary angiography. Treatment strategies are aimed at addressing the root cause and improving oxygenation, and may include anticoagulant medications for blood clots, treatments for pulmonary hypertension, or surgical interventions in some congenital cases.
